Multi-signature robust video watermarking

2014 1st International Conference on Advanced Technologies for Signal and Image Processing (ATSIP), 2014
Watermarking is a recently developed technique which is currently dominating the world of security and digital processing in order to ensure the protection of digitized trade. The purpose of this work is twofold. It is firstly to establish a state of the art that goes through the existing watermarking methods and their performances.

An ID-based Multi-signature Scheme

Third International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP 2007), 2007
This paper presents an identity-based multi- signature scheme, including the signature protocol and the verification algorithm. Key feature of the proposed scheme is that, the length of the scheme has nothing to do with the number of signatories, and some calculations can be performed beforehand. In addition the security of the scheme is discussed.

Forward-Secure Multi-signatures

2008
In many applications a document needs to be signed by more than one signer. When a signature depends on more than one signer we call it a multi-signature. Further, ordinary digital signatures have an inherent weakness: if the secret key is leaked, then all signatures, even the ones generated before the leak, are no longer trustworthy.

Compact Multi-signatures for Smaller Blockchains

2018
We construct new multi-signature schemes that provide new functionality. Our schemes are designed to reduce the size of the Bitcoin blockchain, but are useful in many other settings where multi-signatures are needed. All our constructions support both signature compression and public-key aggregation.

An Ordered Multi-proxy Multi-signature Scheme

2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008
Recently, Hwang and Chen proposed a new multi-proxy multi-signature scheme. In this paper, an improvement on Hwang et. al. scheme will be proposed. It is more efficient in terms of computational complexity and communication cost. Furthermore, the security of the new scheme is based on the difficulty of factoring large numbers.

An Anonymous Proxy Multi-signature with Accountablility

2015
A proxy signature scheme enables a signer to delegate its signing rights to any other user, called the proxy signer, to produce a signature on its behalf. In a proxy multi-signature scheme, the proxy signer can produce one single signature on behalf of multiple original signers.

Proxy multi-signature binding positioning protocol

2014 IEEE/CIC International Conference on Communications in China (ICCC), 2014
Position-based cryptography has attracted lots of researchers' attention. In the mobile Internet, there are many position-based security applications. For the first time, one new conception-proxy multi-signature binding positioning protocols, is proposed.

REALIZABLE QUANTUM BROADCASTING MULTI-SIGNATURE SCHEME

International Journal of Modern Physics B, 2008
Two quantum broadcasting multi-signature schemes are presented: one is used to sign classical digital messages and the other to sign quantum messages. The quantum one-way function is used to realize signature and verification in the digital multi-signature scheme, while quantum teleportation is used in the quantum multi-signature scheme.
